TECHNICAL FIELD

The present disclosure relates to a wearable device for generating an image signal, and a system for controlling the same, and more particularly, to a wearable device connected to a user biometric state measurement device to capture an image of a certain place or situation, and a system for remotely controlling the wearable device and the user biometric state measurement device in real time.

BACKGROUND ART

Recently, wearable devices have emerged. Wearable devices have generally appeared in the form of glasses connected to smartphones or as bands worn on the wrist and, in recent years, have also been able to operate independently of smartphones.

Further, as the wearable device-related technology has been developed, wearable devices may be implemented to have other shapes, such as a helmet worn on the head, in addition to glasses or a band worn on the wrist.

Meanwhile, when an accident such as a fire or an injury in a remote area occurs, in the case of an affected person waiting for rescue or a rescuer about to enter the scene of the accident to aid the affected person, accurate judgment regarding the current status of the event having caused the accident or risks which will be faced by rescuers, as well as the current status of the affected person, may be required to prevent further damage from occurring and to allow the affected person to be safely rescued.

For example, when a fire has occurred in the middle stories of a building consisting of a plurality of stories, in order for a person removed from the scene of the fire by a certain distance to save another person in danger in the fire scene, the person needs to judge a situation at the scene of the fire accurately to determine a safe, quick rescue method, and may determine the current state of the person at the scene of the fire accurately to determine a precise rescue time.

In general, a person distant from an endangered person may use cell phones or radios to receive information on the surroundings or physical condition of the endangered person. However, these methods are difficult to use in the case that urgent rescue is required in the above-mentioned fire or injury situation, as well as in the case that it is impossible to perform remote communications or perform communications in real time, or if it is only possible to transmit information regarding the situation with audio or visual data. Thus, it may be difficult to accurately send information on the surroundings or physical condition of an endangered person to others over a long distance.

As a concrete example of such a situation, accidents occurred because, when rescuers entered the World Trade Tower in the September 11 terrorist attacks and rescued people in the accident situation, accurate information regarding the situation at the site and the current status of endangered persons was not sent to a rescue center, such that the rescuers, as well as people at the site of the accident, were in danger, or died.

As described above, events and accidents continue to occur around us. In addition, even though information regarding the physical condition or surroundings of endangered persons needs to be frequently sent to others in a remote location, a technology for a person distant from an endangered person to accurately determine the situation in the surroundings or physical condition of endangered persons does not exist.

Thus, as a method for solving such a problem, a need exists for a means for enabling a person in a predetermined environment to accurately transmit his or her situation or physical condition to a person at a distant location using images. On the other hand, there is a demand for a means for enabling a person at a distant location to free a specific person from a predetermined environment or to accurately confirm information on the surroundings or physical condition of the specific person in order to aid the specific person.

Referring to FIG. 2, a wearable device 100 to which the exemplary embodiment in the present disclosure may be applied may include a camera unit 120, a voice input unit 113, a user input unit 112, 114, a sensing unit 130, an output device 300, a wireless communications unit 250 (a communications module), a memory 260, an interface unit 270, a control unit 210, a context evaluation module 230, a voice recognition unit 220, and a power supply unit.

The camera unit 120 may be provided to input a video signal or an image signal, and two or more camera units 120 may also be provided, depending on the configuration of the wearable device. The camera unit 120 may process an image frame, such as a still image or a video, obtained by an image sensor in a video call mode or an image pick-up mode. The processed image frame may be displayed on a display unit 310. Further, the image frame, processed by the camera unit 120, may be stored in the memory 260 or transmitted to an external device through the wireless communications unit 250 (the communications module). Further, when the image signal or the video signal is used as an input for information processing, the camera unit 120 may transmit the image signal or the video signal to the control unit 210.

The voice input unit 113 may be provided to input a voice signal, and may include a microphone or the like. The microphone may receive an external audio signal in a call mode, a recording mode, or a voice recognition mode to process the external audio signal into electrical voice data. The processed voice data may be converted into a transmissible format and may be output to a mobile communications base station through a mobile communications unit in the call mode. The microphone may use various types of noise removal algorithms for removing noise generated when receiving the external audio signal.

The user input unit 112, 114 may generate key input data that a user enters to control operations of the wearable device. The user input unit 112, 114 may include a keypad, a keyboard, a dome switch, a capacitive or resistive touchpad, a jog wheel, a jog switch, or a finger mouse. In particular, when the touchpad forms a layer structure together with the display unit 310 to be described later, this may be referred to as a “touchscreen”.

The sensing unit 130 (a sensor) may sense the current state of the wearable device, such as an open and closed state of the wearable device, a location of the wearable device, or the presence or absence of a contact by the user with the wearable device, to generate a sensing signal for controlling operations of the wearable device. Further, the sensing unit 130 may function as an input unit, receiving an input signal for information processing performed by the wearable device, and may perform various sensing functions, such as recognizing whether the external device connects to the wearable device.

The sensing unit 130 may include a gyro sensor 131, an acceleration sensor 132, a pressure sensor 133, an iris recognition sensor 134, a heart rate sensor 135, and an electromyogram (EMG) sensor 136, and may also include types of sensors currently developed or commercialized and sensors to be developed in the future, such as a skin temperature sensor, a skin resistance sensor, an electrocardiogram (ECG) sensor, an ultraviolet (UV) sensor, a body oxygen sensor, a motion sensor, a fingerprint recognition sensor, a proximity sensor, a nitrogen sensor, and a carbon monoxide sensor.

The pressure sensor 133 may detect whether pressure is applied to the wearable device, the magnitude of the applied pressure, or the like. The pressure sensor 133 may be provided in a portion of the wearable device in which pressure detection is required, depending on a service environment. When the pressure sensor 133 is installed in the display unit 310, a touch input through the display unit 310 and a pressure touch input at which pressure higher than that of the touch input is applied to the display unit 310 may be identified according to a signal output from the pressure sensor 133. Further, according to the signal output from the pressure sensor 133, the magnitude of pressure applied to the display unit 310 at the pressure touch input may be identified.

The motion sensor may include at least one of the gyro sensor 131, the acceleration sensor 132, and a geomagnetic sensor, and may sense a location or movement of the wearable device using the at least one sensor. The acceleration sensor 132 usable in the motion sensor may be a device, converting a change in acceleration in a direction thereof into an electrical signal, and may be widely used with the development of micro-electro-mechanical systems (MEMS) technology. The acceleration sensor 132 may include a gravity sensor, identifying a change in gravitational acceleration. When used with a Bluetooth® v. 4.0 or higher Bluetooth® low energy (BLE)-based beacon, such as v. 4.2, capable of active sensing, the acceleration sensor 132 may identify whether the user passes a specific location and move on the specific location at a moving speed, thus measuring an accurate time in relation to the moving speed. Further, the gyro sensor 131 may measure an angular speed, and may sense a turning direction with respect to a reference direction.

The iris recognition sensor 134 may function to recognize a person using iris information of eyeballs having characteristics inherent to each person. The human iris is completely formed in the 18 months after birth. Once formed, the round iris pattern protruding close to the medial side of the iris rarely changes, and also has a unique shape in every person. Thus, iris recognition may be the application of different iris characteristics computerized for each person to security authentication technology. That is, iris recognition is an authentication method developed as a means of identifying a person by analyzing the shape and color of iris, the morphology of retinal capillaries, or the like, of the person.

The iris recognition sensor 134 may encode an iris pattern, convert an iris code into an image signal, and compare and determine the image signal. The general working principle is as follows. First, when the user's eyes are focused on a mirror in the center of an iris recognizer at a predetermined distance, an infrared camera may be focused using a zoom lens. Subsequently, an iris camera images the user's irises, an iris recognition algorithm may analyze a contrast pattern of the irises by area to generate an iris code unique to an individual. Finally, a comparison and search process may be performed while registering the iris code in a database.

The heart rate sensor 135 may detect a change in photoplethysmogram (PPG), according to a change of a blood vessel thickness, caused by a heartbeat, in order to collect an emotional signal. Furthermore, the heart rate sensor 135 may measure a heart rate per unit time, a heart rate change. When measuring the heart rate per unit time, the heart rate sensor may also measure the heart rate in consideration of a state of surroundings and a state of an object to be measured.

The skin temperature sensor (a body temperature sensor) may include a skin condition sensor, and may measure a skin temperature, according to a change in a resistance value, in response to a change in an ambient temperature, as well as measure a body temperature. The skin temperature sensor may also measure an abnormal rise or fall in the skin temperature, based on a predetermined value, for example, a normal skin temperature of 36.5° C. to 37.5° C. Further, the skin resistance sensor may measure electrical resistance from skin to be used for the skin temperature sensor to measure the skin temperature, according to the change in the resistance value, in response to the change in the ambient temperature.

The UV sensor may detect ultraviolet light, and when a fire has occurred, the UV sensor may detect the fire. For example, when smoke is generated by a fire to block light received by the UV sensor, the amount of UV light that may be detected by the UV sensor may be changed, and thus the UV sensor may measure the changed amount of UV light to sense whether a fire has occurred.

Further, when smoke generated by a fire blocks light illuminated by the UV sensor to a particular place, the UV sensor may detect or determine whether a fire has occurred and the size of the fire, according to an extent that the light is blocked, and may also calculate a saturation of the smoke per unit area, based on the size of the fire determined through the UV light analysis or processing described above.

The body oxygen sensor may measure the amount of oxygen present in the human body, and may refer to a sensor that when the human body in an average condition has the amount of oxygen within a normal range, previously determines various conditions, for example, such as body temperature, ambient temperature, and heart rate, determines the amount of oxygen present in the human body in consideration of changes in the various conditions, and measures the determination result.

The proximity sensor may detect an approaching object, or the presence or absence of an adjacent object, without mechanical contact therewith. The proximity sensor may detect the adjacent object using a change in an alternating current (AC) magnetic field or in a static magnetic field, or using a change rate of capacitance. Two or more proximity sensors may be provided according to configuration types.

The carbon monoxide sensor may measure the concentration of carbon dioxide gas present in the adjacent air, and may use a method of optically measuring the concentration of carbon dioxide using non-dispersive infrared (NDIR) or a method of electrochemically measuring the concentration of carbon dioxide using a solid electrolyte.

The nitrogen sensor may measure the concentration of a nitrogen oxide present in the adjacent air, such as nitrogen monoxide (NO), nitrogen dioxide (NO₂), dinitrogen trioxide (N₂O₃) or nitrous oxide (N₂O), and may use a method using equilibrium potential, a method using current, a method using a conversion cell that converts nitrogen oxide gas into other gas form, or a method using an oxygen-ion conductive solid electrolyte and an electrical signal.

The output device 300 may output an audio signal, a video signal, or an alarm signal. The output device 300 may include the display unit 310, an audio output module, an alarm unit 330, and a haptic module 340.

The display unit 310 may display information processed by the wearable device. For example, when the wearable device is in the call mode, the display unit 310 may display a user interface (UI) or a graphical user interface (GUI). When the wearable device is in the video call mode or the image pick-up mode, the display unit 310 may display captured and received images respectively or simultaneously, and may display the UI or GUI.

Meanwhile, as described above, when the display unit 310 and the touchpad form the layer structure to make up a touchscreen, the display unit 310 may also be used as an input device, other than an output device. When the display unit 310 includes the touchscreen, examples of the touchscreen may include a touchscreen panel and a touchscreen panel controller.

In addition, the display unit 310 may include at least one of a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, and a 3D display. Two or more display units 310 may also be provided according to types of the wearable device. For example, the wearable device may include an external display unit 310 and an internal display unit 310 simultaneously.

The display unit 310 may be implemented as a head-up display (HUD) or a head-mounted display (HMD). The HMD is an image display device that the user may wear on his or her head as glasses to enjoy a large-scale image. The HUD is an image display device that may project a virtual image onto a clear panel within the user's field of view.

The audio output module 320 may output audio data, received from the wireless communications unit or stored in the memory 260, in a call reception mode, the call mode or the recording mode, the voice recognition mode, and a broadcast reception mode. Further, the audio output module 320 may perform a function of the wearable device, for example, outputting an audio signal associated with a call ringtone or a message ringtone. The audio output module 320 may include a speaker or a buzzer.

The alarm unit 330 may output a signal for providing a notification of an occurrence of an event by the wearable device. Examples of the event, generated by the wearable device, may include call signal reception, message reception, or key signal input. The alarm unit 330 may output the signal for providing a notification of an occurrence of an event in format different from an audio signal or a video signal. For example, the alarm unit 330 may include a vibration alarm unit to output a signal in a vibration manner. When a call signal or a message is received in the wearable device, the alarm unit 330 may output a signal for providing a notification of the received call signal or message. Further, when a key signal is input to the wearable device, the alarm unit 330 may output a signal as feedback on the input of the key signal. The signal, output by the alarm unit 330, may enable the user to recognize an occurrence of an event. The wearable device may also output a signal for providing a notification of an occurrence of an event through the display unit 310 or the audio output module.

The haptic module 340 may create various haptic effects that the user may feel. A typical example of the various haptic effects, created by the haptic module 340, may include a vibration effect. When the haptic module 340 generates a vibration as a haptic effect, the haptic module 340 may change the strength and pattern of the vibration, and may also combine and output different vibrations, or sequentially output different vibrations.

The broadcast-related information may exist in various forms.

The broadcast reception module may receive the broadcast signal using various types of broadcast systems, and may receive a digital broadcast signal using a digital broadcast system.

Bluetooth® v. 4.2 may enable the wearable device to communicate with devices within an about 100 m radius of the wearable device, and may consume less power to hardly affect the battery life to significantly reduce wastage of power, thus seamlessly being activated.

Further, Bluetooth® v. 4.2 may enable a Bluetooth® sensor or devices to directly access the Internet with the development of Internet protocol support profile (IPSP). In addition, IPSP may enable an unlimited Internet address system, IPv6, and IPv6 over low power wireless personal area networks (6LoWPAN), a low-power wireless communications technology, to apply to Bluetooth®.

Moreover, Bluetooth® v. 4.2 may increase security through supporting of 128-bit advanced encryption standard (AES) encryption, increase its data rate by 2.5 times or more through increasing of the packet capacity between devices, and further enhance power consumption efficiency.

Depending on the above-mentioned features, Bluetooth® v. 4.2 may enable a Bluetooth® sensor or device to directly access the Internet, so that the user may transmit Bluetooth® information to a cloud application without a smartphone application and may also view the Bluetooth® information on a web browser.

The GPS module 115 may receive position information from a plurality of GPS satellites, and may measure the current position of the user using the received position information.

Hereinafter, a wearable device for generating an image signal according to exemplary embodiments in the present disclosure, and a system for controlling the same will be described with reference to the drawings.

FIG. 3 is a diagram illustrating a wearable device generating an image signal according to an exemplary embodiment in the present disclosure.

Referring to FIG. 3, an image signal generation device, according to an exemplary embodiment in the present disclosure, may be implemented as a wearable device, having the concept of the IoT device mentioned above in FIG. 2, and accordingly, the image signal generation device may be implemented to include the features of the respective components stated in the description of the wearable device of FIG. 2, even without an additional explanation in FIG. 3.

The image signal generation device 100 may include a frame unit, an image pick-up unit, a battery unit, a wireless communications unit, and a control unit. According to an exemplary embodiment in the present disclosure, the image signal generation device may include or may not include components such as a voice signal output unit, a user input unit, and a position measurement unit. In contrast, the image signal generation device may further include another component included in the wearable device mentioned above in FIG. 2.

Meanwhile, the respective components, included in the image signal generation device of FIG. 3, may perform the same functions as the components included in the wearable device described above in FIG. 2. In an exemplary embodiment in the present disclosure, the image signal generation device may be interpreted as further including a device that may capture a surroundings image, transmit the captured image to a biometric state measurement device and a server, and receive a response to the transmitted captured image therefrom.

In an exemplary embodiment in the present disclosure, the frame unit may be a helmet wearable on the head of the user. As described above, when the frame unit of the wearable device is implemented in helmet form, a user surroundings image, captured by the image pick-up unit included in the wearable device, may be captured from a location of the helmet. Thus, the user surroundings image may be captured from the same point of view as that of the user wearing the helmet.

As a result, according to an exemplary embodiment in the present disclosure, an image, captured from the same point of view as that of the user wearing the helmet, may be generated and provided to the user. When an external device receives the captured image from the wearable device and displays the image, an observer of the external device may observe surroundings of the user from the same point of view as the wearable device's user, even in a remote location. Further, the head of the user, on which the wearable device is worn, may shake relatively less, and when worn on the head of the user, the wearable device may capture an image in a consistent direction, compared to when worn on the wrist, the arms, the body, or the legs of the user. According to an exemplary embodiment in the present disclosure, when the frame unit of the image signal generation device is implemented as the helmet wearable on the head of the user, a captured image may be prevented from being wasted due to a frequent movement of the head.

Meanwhile, according to an exemplary embodiment in the present disclosure, the image signal generation device may receive an alarm signal from the biometric state measurement device. Here, the alarm signal may refer to a signal transmitted in the case that, when a value, represented by a biometric signal of the biometric state measurement device's user, is compared with a value, represented by an existing biometric state result received from the external device, or with a predetermined reference value, the values differ from each other by an amount equal to the predetermined value or more. The image signal generation device may capture a user surroundings image, using a camera included in the image pick-up unit, in response to the reception of the alarm signal. The image pick-up unit (or a camera unit) may include, as illustrated in FIG. 4, a lens used for image capturing, an image sensor, a serializer/deserializer (SerDes) transmitter (TX) used to transmit a captured image, and a microcomputer (MICOM), a processor controlling the image pick-up unit. The image pick-up unit may further capture at least one of a lateral image and a rear image, as well as a front image, when capturing the user surroundings image using the camera, and may include audio, audio information, other than a video image, visual information, when capturing the above images.

Further, the image signal generation device may include the position measurement unit, which may measure a position of the image signal generation device's user, using the GPS or BLE, under the control of the control unit.

In more detail, when a device exists, transmitting a beacon usable to measure a position in any space or building in which various kinds of disaster, including a fire, may occur, the image signal generation device may connect to the device to receive the beacon from the device, and may measure the position of the user wearing the image signal generation device by transmitting position information thereof to a predetermined external device, based on the received beacon.

Furthermore, the measuring of the position of the user wearing the image signal generation device may also be performed by the image signal generation device itself using the GPS and the camera.

As described above, as it is possible to measure the position of the user wearing the image signal generation device, a person in a remote location may be able to determine the current position of the user wearing the image signal generation device, as well as help the image signal generation device's user to move accurately quickly by transmitting route information to the image signal generation device or transmitting and receiving a voice signal through a voice communications unit (or the voice signal output unit) included in the image signal generation device, as illustrated in FIG. 4.

Meanwhile, the image signal generation device that has performed the surroundings image capturing or the position measurement may generate an image signal, including the captured image, or user position measurement information, including user position information, and may transmit the generated image signal and user position measurement information to the external device (for example, all devices, such as a PC, a smartphone, or a server, connectable to the image signal generation device through wired and wireless communications) through the wireless communications unit (or a modem unit) of the image signal generation device illustrated in FIGS. 3 and 4. The above transmission may be performed using a short-range communications module, using a scheme such as Bluetooth® or the like, or using a wireless Internet module, including an LTE module.

As previously mentioned, according to an exemplary embodiment in the present disclosure, when the image signal generation device includes an LTE communications module for transmitting a communications signal to, and receiving a communications signal from, at least one external device, the image signal generation device may be connected to the external device (for example, the server or the remote monitoring device) in a remote location through the LTE communications module in real time, and may further transmit a communications signal to, and receive a communications signal from, the external device through the LTE communications module.

Thus, according to an exemplary embodiment in the present disclosure, since the image signal generation device may transmit the communications signal to, and receive the communications signal from, the external device in a relatively wider range, compared to the short-range communications module (for example, a Zigbee® or Bluetooth® communications module) that may transmit and receive a communications signal only within a predetermined short range, the wearable device, according to an exemplary embodiment in the present disclosure, that reduces restrictions on the transmission and reception range may be very useful in an emergency situation, such as a fire or disaster, that frequently requires long-range communications.

Further, upon transmitting the communications signal, the image signal generation device may directly transmit the communications signal to the external device, or may also transmit the communications signal to the external device through a relay station within a predetermined radius of the user.

Here, the relay station may refer to a small cell for low power/short-range communications, for example, a pico cell or a femto cell. Merely, at the scene of a fire, all fixed relay stations, as described above, may be destroyed by the fire, and thus the relay station may include a small device, having mobility, (for example, a relay station attached to a ladder truck located outside a building in which a fire has occurred, or a mobile relay station (a small cell) implemented to be suitable for a firefighter to throw when entering the building to extinguish a fire.

Further, the captured image and the user position measurement information may be stored in the memory unit or the memory for performing a storage function within the image signal generation device, and the transmitting and the storing may be performed simultaneously or individually.

Moreover, the image signal generation device may further include a wireless communications unit (a communications modem) used to transmit the captured image or the like, and the wireless communications unit may be detachably attached inside or outside the image signal generation device. Further, the wireless communications unit may further include a battery to further reduce power consumption of the image signal generation device, and the battery may also be included in the image signal generation device.

At this time, the battery may be implemented as a lithium-ion battery, using a liquid electrolyte and having a high level of energy storage density, a lithium-ion polymer battery, using a solid- or gel-polymer as an electrolyte and having a light weight, a low level of internal resistance, and heat resistance, as well as a high level of energy storage density, thus achieving a high level of stability, or a lithium iron phosphate (LiFePO4) battery, having a structure in which phosphorus and oxygen are tightly bonded to prevent oxygen from being generated at high temperatures, thus being safe from a fire and explosion. However, this is only an example, and the battery may be implemented using all batteries, having been developed up to date or which will be developed in the future.

Further, the battery may be implemented as an ultra small, ultra slim, or flexible battery, and may be charged using a wireless charging technology using any one of a magnetic induction method and a magnetic resonance method.

Here, the magnetic induction method may enable a power source to supply power to a power destination in a short location using magnetic field resonance, and may refer to a method of charging the battery of the image signal generation device by an amount equal to power consumed, when the image signal generation device and a charger face each other at a predetermined distance. For example, in the case that the charger is installed together with the image signal generation device in a place in which the image signal generation device is stored, when the image signal generation device is stored in the place when not in use, or placed on the charger, the image signal generation device and the charger may maintain a predetermined distance therebetween, so that the battery of the image signal generation device may be charged by an amount equal to an amount of power consumed.

Further, the magnetic resonance method may enable a power source to wirelessly supply power to a power destination in a remote location using an internal coil, and may be a method capable of supplying power to a relatively remote distance, compared to the magnetic induction method.

Meanwhile, according to another exemplary embodiment in the present disclosure, the image signal generation device may perform or control the image capturing, the position measurement, the storing of the image signal, including the captured image, and the user position measurement information, including the position information, in the memory unit or the transmitting of the image signal and the user position measurement information to the external device, not by the alarm signal received from the biometric state measurement device, but by the user's instruction input through the user input unit.

Further, the biometric state measurement device, according to an exemplary embodiment in the present invention, may be implemented as a helmet-type wearable device, a glasses-type wearable device, an external remote controller, a bracelet, or a ring. However, these are only examples, and the biometric state measurement device may have any other form. Moreover, although not illustrated in FIG. 3, the image signal generation device may also be manufactured to include all configurations and operations of a biometric state measurement device to be described in FIG. 6 below.

FIG. 5 is a flowchart illustrating a process of connecting a cell phone to a wearable device generating an image signal according to an exemplary embodiment in the present disclosure.

Referring to FIG. 5, when an image signal generation device is powered on to transition from an idle state to an active state, the image signal generation device may connect to (or access) other external device (for example, a biometric state measurement device or a cell phone) to transmit a captured image thereto (S501, S502). For convenience of explanation, the external device may be assumed to be a biometric state measurement device.

At this time, the connection may also be formed between the image signal generation device and the biometric state measurement device in a device-to-device (D2D) manner or by relay by a base station after a random access procedure on the base station.

In contrast, when the connection (access) fails, the image signal generation device may attempt to connect to the biometric state measurement device, according to settings, until the connection is successful (S503). When the connection (access) is successful (S504), the image signal generation device may transmit information on the image signal generation device and a key value to the biometric state measurement device (S505).

At this time, the key value may refer to a unique identification number of the image signal generation device, and may be previously stored in a related server. Thus, the biometric state measurement device that has received the key value from the image signal generation device may go through a procedure of confirming the key value of the image signal generation device through the server, and may connect to (access) the image signal generation device when the received key value matches the key value previously stored in the server, so that the image signal generation device may transmit the captured image to the biometric state measurement device or receive a control command from the biometric state measurement device (S506, S507).

When the key value, received from the image signal generation device, does not match the key value previously stored in the server, the biometric state measurement device may refuse to perform the connection (access), or may interrupt it (S506, S508).

FIG. 6 is a block diagram illustrating a biometric state measurement device according to an exemplary embodiment in the present disclosure.

Referring to FIG. 6, the biometric state measurement device 200, according to an exemplary embodiment in the present disclosure, may be implemented as the wearable device described above in FIG. 2, and accordingly, may include the features of the respective components mentioned in the description of the wearable device.

The biometric state measurement device 200 may include a biometric signal measurement unit 601, a wireless communications unit 602, a position measurement unit 603, a control unit 604, and a manual input unit 605. Although not illustrated in FIG. 6, the biometric state measurement device 200 may further include a frame for wearing the biometric state measurement device 200 on the body of a user. Further, according to an exemplary embodiment in the present disclosure, the biometric state measurement device 200 may not include the above components, or may also include another component included in the wearable device described above in FIG. 2.

Meanwhile, the biometric signal measurement unit 601 of the biometric state measurement device 200 may sense or detect a user biometric signal, and for this purpose, may generate a sensing signal.

That is, the biometric state measurement device may be worn on the body of the user wearing the helmet to measure at least one type of biometric signal information among user heart rate, user body temperature, user skin condition, user body oxygen amount, user surroundings nitrogen amount, user surroundings carbon monoxide amount, and user surroundings ultraviolet light change.

Here, the user biometric signal may include user heart rate, user body temperature, user skin condition, user body oxygen amount, user surroundings nitrogen amount or user surroundings carbon monoxide amount, and user surroundings ultraviolet light change, and may further include all of the biometric signals that may be measured by the sensing unit 130, as mentioned above in FIG. 2.

Further, the biometric signal measurement unit may include all of a gyro sensor, an acceleration sensor, a proximity sensor, a pressure sensor, a motion sensor, a fingerprint recognition sensor, an iris recognition sensor, a heart rate sensor (a heart rate detector sensor), a body temperature sensor, a skin condition sensor (a skin temperature sensor), a skin resistance sensor, an ECG sensor, a UV sensor, and a body oxygen sensor (an oxygen amount sensor).

For convenience of explanation, it is assumed that the biometric signal measurement unit includes, as illustrated in FIG. 7, a heart rate sensor, measuring a user heart rate, an acceleration sensor, measuring whether the user moves and a moving speed thereof, a body temperature sensor, measuring a user body temperature, a skin condition sensor, measuring a user skin condition, and a UV sensor, measuring a user surroundings ultraviolet light change.

Merely, the biometric signal measurement unit, illustrated in FIG. 7, may further include other sensors, such as an oxygen amount sensor, measuring a user body oxygen amount, a nitrogen amount sensor, measuring a nitrogen amount within a predetermined radius of the user, and a carbon monoxide amount sensor, measuring a carbon monoxide amount within a predetermined radius of the user, as mentioned above.

In an exemplary embodiment in the present disclosure, the biometric state measurement device 200 may measure the biometric signal of the user wearing the biometric state measurement device through the biometric signal measurement unit.

For example, when the user wearing the biometric state measurement device is exposed to the scene of a fire, the body temperature sensor of the biometric state measurement device may measure a change in a user body temperature due to heat generated by the fire, and the heart rate sensor may measure a change in a user heart rate, caused by the fire or the change in the user body temperature, by determining a change in a resistance value.

Further, when the user has difficulty in breathing due to smoke generated by the fire, so that the amount of oxygen present in the body of the user rapidly changes, the oxygen amount sensor may measure a change in the oxygen amount, and the UV sensor may measure a change in UV light around the user, using the method described above in FIG. 2, so as to detect whether the fire has occurred and the size of the fire.

For another example, when the user wearing the biometric state measurement device meets with an accident on a high, freezing mountain, the body temperature of the user may drop rapidly, and the body temperature sensor, measuring the user body temperature, may detect whether the user body temperature is changed with respect to a predetermined reference value and how much the user body temperature is changed, i.e., variation of the change.

Further, the skin condition measurement sensor included in the biometric state measurement device may also detect that the skin of the user is frostbitten due to a rapid drop in the user body temperature.

Meanwhile, the biometric state measurement device 200 may determine a user biometric state using the measured user biometric signal.

In more detail, according to an exemplary embodiment in the present disclosure, the biometric state measurement device may receive the existing biometric state result of the user from the external device, may compare the value, represented by the received existing biometric state result of the user, to the value, represented by the sensed user biometric signal, and may determine whether the value, represented by the sensed user biometric signal, differs from the value, represented by the received existing biometric state result, by an amount equal to the predetermined value or more, to determine the user biometric state.

Further, according to an another exemplary embodiment in the present disclosure, the biometric state measurement device may compare a reference value, preset by the biometric state measurement device itself, to the value, represented by the sensed user biometric signal, without using the existing biometric state result received from the external device as described above, and may determine whether the preset reference value differs from the value, represented by the sensed user biometric signal, by an amount equal to the predetermined value or more, to determine the user biometric state.

Here, the determining of the user biometric state may refer to a process of determining whether the user body temperature, the user heart rate, or the user skin condition that may be measured when the user is in a normal state has changed to the extent that user body temperature, the user heart rate, or the user skin condition reaches a predetermined risk level, according to changes in a user surroundings environment, and the determining of the user biometric state may be performed by the control unit of the biometric state measurement device.

Further, according to an exemplary embodiment in the present disclosure, when the biometric state measurement device includes a plurality of sensors, the biometric state measurement device may compare a biometric signal value, measured by at least one of the plurality of sensors, to the predetermined reference value, and may determine whether the measured biometric signal value differs from the predetermined reference value by an amount equal to the predetermined value or more. In contrast, when each of the plurality of sensors is previously prioritized, the biometric state measurement device may compare a biometric signal value, measured by a particular sensor having a high priority, of the plurality of sensors, to the predetermined value, and may determine whether the measured biometric signal value differs from the predetermined reference value by an amount equal to the predetermined value or more.

Meanwhile, the biometric state measurement device that has determined the user biometric state may generate an alarm signal, including the user biometric signal, in the case that the biometric state result has determined that the value, represented by the sensed or measured user biometric signal, differs from the value, represented by the existing biometric state result received from the external device, or the predetermined reference value, by an amount equal to the predetermined value or more, upon comparing the value, represented by the sensed or measured user biometric signal, to the value, represented by the existing biometric state result received from the external device, or the predetermined reference value.

The biometric state measurement device may transmit the generated alarm signal to the external device (for example, all devices connectable to the biometric state measurement device, such as a PC, a smartphone, or a server) through the wireless communications unit (or the communications modem). At this time, the transmitting may be performed using the short-range communications module or the wireless Internet module, particularly, a BLE module included in the biometric state measurement device.

Further, the biometric state measurement device may include the position measurement unit, which may measure a position of the biometric state measurement device's user using the GPS or BLE under the control of the control unit, and which may transmit the position measurement result to the external device through the wireless communications unit. The position measurement unit may perform the same function as the position measurement unit of the image signal generation device mentioned above in FIG. 3.

The alarm signal and the position information including the user biometric signal that have been transmitted to the external device through the above process may trigger capturing an image and transmitting the captured image by the image signal generation device according to an exemplary embodiment in the present disclosure, and may also be used to monitor or store the captured image and the position information on the external device.

Meanwhile, the sensing of the user biometric signal, the determining of the user biometric state, and the transmitting of the alarm signal may be controlled by the user, or may be remotely controlled by the external device connected to the biometric state measurement device, according to an exemplary embodiment in the present disclosure.

Meanwhile, the biometric state measurement device, according to an exemplary embodiment in the present disclosure, may be implemented as various forms such as a wristband-type wearable device or a glasses-type wearable device, an external remote controller, a bracelet, or a ring. However, this is only an example, and the biometric state measurement device may have any other form.

FIG. 8 is a flowchart illustrating a method of remotely monitoring a biometric state measurement device and a wearable device generating an image signal according to an exemplary embodiment in the present disclosure.

A system, remotely monitoring a physical condition, may include an image signal generation device 100, a biometric state measurement device 200, and a server 300. Here, the server 300 may refer to an external device or a device, such as a PC or a smartphone, that may be connected to the biometric state measurement device and the image signal generation device through wired and wireless communications.

The system, remotely monitoring a physical condition, will be detailed hereinafter, and descriptions of contents overlapping those described above will be omitted.

Meanwhile, the biometric state measurement device 200 may sense or measure a user biometric signal by the method mentioned above in FIG. 6 (S801). When comparing a value, represented by the user biometric signal, to a value, represented by an existing biometric state result received from the external device, in the case that the biometric state result is determined that the value, represented by the user biometric signal, differs from the value, represented by the existing biometric state result received from the external device, or a predetermined reference value, by an amount equal to the predetermined value or more, the biometric state measurement device 200 may transmit an alarm signal to the image signal generation device 100 and the server 300 (SS802, S803).

The server 300 that has received the alarm signal from the biometric state measurement device 200 may receive an image signal, including an image captured by the image signal generation device, from the image signal generation device, in response to an indication of the sensed biometric signal (S804, S805).

Further, although not illustrated in FIG. 8, the server 300 may also receive user position measurement information of the image signal generation device's user from the image signal generation device.

Meanwhile, according to an exemplary embodiment in the present disclosure, the server 300 that has received the image signal may transmit an image quality control message to the image signal generation device (S806), and may receive a captured image, having image quality of a predetermined standard or higher, from the image signal generation device, in response to the image quality control message (S807).

At this time, the image quality control message may refer to a message instructing the image signal generation device to interrupt the current image capturing thereof and to capture an image, having image quality of a predetermined standard or higher, from a point in time at which the image quality control message is received, and according to an exemplary embodiment in the present disclosure, the image quality control message may also include an instruction to adjust the frame rate, in addition to the instruction to control the image quality.

Further, the predetermined standard may be previously set as any one of image resolutions such as SD (D1(720×480), HD (1280×720), and full HD (1920×1080) and any one video codec compression method of MPEG-4, H.264, and H.265. However, this is only an example, and the predetermined standard may also be set as a different range of criteria.

Meanwhile, the server 300 that has received the user biometric signal and the image signal from the image signal generation device 100 and the biometric state measurement device 200 may divide and store the received user biometric signal and image signal by users, and may output the user biometric signal and the image signal through a display to monitor the user biometric signal and the image signal.

Further, the server 300 may compile statistics of the user biometric signal and the image signal, divided and stored by users, according to a preset method, and may output the statistical results through the display. The preset method may include all methods of compiling statistics of data.

Meanwhile, the server 300 that has received the image signal and the user position measurement information may transmit a control signal, including a control command, to the user of the biometric state measurement device and the image signal generation device, in consideration of a context based on the received image signal and user position measurement information, and the control signal may include a voice signal to be transmitted to the user, and the control command for controlling the biometric state measurement device and the image signal generation device (S808, S809).
